Application led November 9, 1887. Serial No; 254,673. (No model) To @ZZ whom it may concern,.- y

Be it lknown that I, FEEDEEICK H. FURNIss, a citizen of the United States, and a resident of IVaterloo, in the county of Seneca and State of 5 New York, have invented certain new and useful Improvements in Drive Well Points, 'of

which the following is a specification.

My yinventionwrelates to that class of Wells now commonly known as drivenj7 wells or .Q drive7 wells. Heretofore the lower end of the well-has consisted of a more orless sharp or tapering part or point7 to facilitate its passage into the earth, and this point has been adapted to bear the force required and the re-A sand, clay, or other obstructions, and for theA z5 purpose of preventing this clogging or obstruction the point has been movably connected to the tube in such a manner that the ports could be closed while the well was being driven and opened when water was reached.

. 3o This attempt, however, to prevent the clogging of the ports and tube has, so far as I am aware, been only partially successful, and the principal purpose o f my invention is to'provide improved means for protecting the ports while the'well is being driven and allowing a free entrance of water after a supply has been reached. I also aim to improve the well in other respects, all of which will be more fully explained hereinafter.

acteristic features of my invention; but to enable others more fully to understand my improvements I will describe them with greater particularity, referring to the accompanying drawings, in which- Figurel is a side elevationk of the lower part f or portion of a drive-well embodying my invention, and yshowing the parts in the position they occupy while the well is being driven. 5o Fig: 2-is a vertical central section through the parts shown in Fig. 1, excepting that in Fig.

I have set forth in separate claims the ch'ar- 2 the partsare shown in the'position they occupy vwhen arranged to admit the water; and

,Fig Sis a side elevation'of the' driven welly when ready for use. I

Like letters of referenceindcate lkeparts. A represents thepoin't.: This point consists of a tapering or pointed portion, a, of an y'anl nular portion or ring, b, and of arms or bars y c @connecting the part a tothe part b, andf6o supporting the latter considerably above the formerhsubstantially as shown. Ihave also *shown astud orexte'nsioind, projecting upward centrally from the part a; butI desire to v state that'while I deemit preferable to em- 65 L ploy this stud as an auxiliary in retaining the point in a vertical position while being driven, I and asl an element of additional strength, I do v notregarditasan absolutely essential accompaniment to certain features of my invent-ion', as 7o Willhereinafter more fully appear. I do not therefore herefintendto be restricted to the `said stud, excepting as indicated specifically in my claims; neither do I intend to claimthe' v same broadly, as it is not new with me in that sense. V- v.

B is the well-tube. Y Thisy tube mayfconsist of as many sections as may be required,the

sections each being of such length as r,maybe expedient, and being coupled together 1n the 8o usual manner-for example, by means of coup-t lers e e.y The lowerend ofthe lower section v of tubingpasses down freely through the ring or hoop b, andfis ajcollar on said end. 'The collar f is of such size as to be capable of bey l Vingmoved up and down freely'between the bars or arms c c, but incapable of. being drawn up through the ring or hoop b., I deem it best to make'the collarf removable, preferably by making it internally ScreW-imreadedv and by 9o making corresponding screw-threads on the I 'f lower end of the tubing.

The well is drivenI in the usual manner or in' any suitable way,when, as willbe perceived,

the blows or the'pressurewill carry the collar 95 f downtupon thenpper enkdor face of the part a of the point A if the said c'ollary be,A not al1v ready seated thereonv by reason of gravity. The stud d will then be inthe lower end 'or part of the tube B 'and aid in preventing'the frco y' point Arfrom being tilted laterally asfit resiste the pressure upon itwhile it is being driven, but the arms or bars c c, in co-operation with the :ring or hoop b, may in many casesbe sufficient for that purpose, or may be made so.

It will be perceived, especially on reference to Fig. l, that the lower end of the tube is completely closed when the collar f rests on the parta, and that there are then no openings or water ports which can become filled or clogged While the parts are in that position or while the well is being driven.

After the Well has been driven sufliciently low to bring the point A into or somewhat below a Vein or" Water-in other words,-When a supply of Water has been reached or tapped- I raise the Well-tubing sufficiently to carry the collar f above the stud d, (or above the upper end of the part a when such a stud is not employed,) and if need be up to or against the ring or hoop d. It will be observed that the lower end of the Welltube will then be Wholly open and unobstructed, and that the water will have free access thereto, and may be drawn up through it and discharged by means of any ordinary pump in operative connection with the tubing-in other words, the capacity of the Waterinduction is equal to the capacity of the tube.

In case any sand, mud, clay, or other earthy subst-ance should cling to the tube before it is,

raised, such matter would be pushed off by the act of raising the tube; or if the tube and point were raised together, then by the act of pushing down the point by means of a rod inserted for that purpose into the tubing; also, if any obstructing matter should be sucked up into the tube, the latter may be unscrewed from the collarf, raised, cleaned by means of a rod or bar, or otherwise, and returned to and screwed into the said collar without disturbance to the point A and its surroundings. The point may also be drawn up at any time to seek a better supply of Water than that found at the lowest depth to which the well was driven.

I regard the point A as an improved article of manufacture, as it is adapted for the use for which it is intended without a substantial change of form or structure.

Having ythus described my invention, what I claim as new, and desire to secure by Letters Patent, isl 1. As an improved article of manufacture, a drive-Well point consisting of the tapering portion ce, having thereon the vertical central stud, d, the annular part or hoop b, and one or more vertical arms or bars, c c, supporting the part b above the part a without inclosing the space between them, substantially and for the purposes specified.

2. The combination, in a drive-well, of the tube B, the collar f, removably applied to the said tube, the ring or hoop b, the tapering or pointed part a, and one or more arms or hoopsupports, c c, all arranged, substantially as described, With relation to each other, for the purposes specied.

3. The point A, consisting of the tapering part a, the stud d, one or more supports, c c, and the hoop b, in combination with the tube B, having a collar at or near its lower end, substantially as and for the purposes specied.

Signed at Waterloo, in the county of Seneca and State of New York, this 5th day of November, A. D. 1887.
